The percentage of oak trees in park is 7.14% and there are 14 times more trees in the park than giant oak trees.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred.

The total number of trees in a park is = 56

The number of giant oak trees in the park is = 4

To find the percentage of oak trees, use the formula -

(Number of Oak Trees/Total number of trees) × 100

Substitute the values into the formula -

(4/56) × 100

(1/14) × 100

7.14%

The number of times (x) that bigger oaks is lesser in comparison to other trees can be found using the arithmetic operation of division.

The equation is -

4x = 56

x = 56/4

x = 14

Therefore, there are 14 times more trees.

The total surface area and lateral area have a difference of 48 square inches. (Correct choice: D)

In this problem we find a right prism with a rectangular base, of which we must determine its lateral area and its total surface area, both in cubic inches.

Lateral area is the sum of all faces A and C (four rectangles), whereas total surface is the sum of lateral area and all faces B (two rectangles). Area formula for rectangles is shown below:

A = w · l

Where:

Now we proceed to determine the lateral area and the total surface area of the prism:

Lateral area

A' = 2 · (3 in) · (5 in) + 2 · (8 in) · (5 in)

A' = 30 in² + 80 in²

A' = 110 in²

Total surface area

A = A' + 2 · (8 in) · (3 in)

A = 110 in² + 48 in²

A = 158 in²

The table 1  represent the function From the given figure.

What is function ?

The function in mathematical terms is the mapping of each member of a set (named as a domain) to another set of members (named as a codomain). This term has a different meaning from the same word that is used every day, such as "the tool works well." The concept of function is one of the basic concepts of mathematics and any quantitative science. The terms "function", "mapping", "map", "transformation" and "operator" are usually used synonymously.

In function, there are several important terms, including:

The domain is the area of ​​origin of the function f denoted by Df.

Codomain is the area where the f function area is denoted by Kf.

The range is the result area which is a subset of the codomain. The function range f is denoted by Rf.

PROPERTIES OF FUNCTIONS

1. INJECTIVE FUNCTION

Called one-on-one function. Suppose the function f represents A to B, then the function f is called a one-on-one function (injective), if each two different elements in A will be mapped to two different elements in B. Furthermore, it can be said briefly that f: A → B is injective function if a ≠ b results in f (a) ≠ f (b) or equivalent if f (a) = f (b) then the effect is a = b.

2. SURJECTIVE FUNCTION

Function f: A → B is called a function to or objective function if and only if for any b in the B domain can be at least one an in domain A so f (a) = b applies. In other words, a codomain of the objective function is the same as its range.

3. BIJECTIVE FUNCTION

A mapping off: A → B is such that f is both an injective and objective function at once, so it is said "f is a function of wisdom" or "A and B are in one-to-one correspondence".

Therefore, The table 1  represent the function From the given figure.

v1 = 200 m / 3 min = 66.7 m/min

v2 = 1000 m / 4 min = 250 m/min

Larry left his home at 9:06 and ran at a constant speed to the lamppost 200 m away. He arrived at the lamppost at 9:09. Immediately after arriving, he turned around and ran to a tree 1000 m away, arriving at 9:13. To find his average velocity during each interval, we can divide the distance traveled by the time it took to travel the distance. For the first interval, Larry traveled 200 m in 3 minutes, so his average velocity was 200 m divided by 3 min, or 66.7 m/min. For the second interval, Larry traveled 1000 m in 4 minutes, so his average velocity was 1000 m divided by 4 min, or 250 m/min.

Answer:

The gas mileages (in miles per gallon) for 35 cars are shown in the frequency distribution. This means that the gas mileage of 35 cars has been recorded and grouped into categories. The categories are 27-30, 31-34, 35-38, and 39-42. The frequency is the number of cars in each category. For example, there are 12 cars that have a gas mileage between 27 and 30 miles per gallon. Approximating the mean of the frequency distribution means finding the average gas mileage of all the 35 cars. To do this, you need to add the gas mileages of all the 35 cars and divide the sum by 35. The approximate mean of the frequency distribution is 33.4 miles per gallon. An analogy that can help you understand this concept is that of a classroom full of students. If you want to calculate the average height of the students, you would need to add up the heights of all the students and divide the sum by the total number of students. The same concept applies to the frequency distribution.

3 teragrams is equal to 3 million grams.

The formula to convert teragrams (tg) to grams (g) is: grams = teragrams x 1000000000000. For example, to convert 15 teragrams to grams, we multiply 15 by 1000000000000, which equals 1.5e+13 or 150000000000000 grams. To convert grams to teragrams, we reverse the formula by dividing grams by 1000000000000. For example, to convert 1500000000000 grams to teragrams, we divide 1500000000000 by 1000000000000, which equals 1.5 teragrams.1 tg (teragram) is equal to 1000000 g (grams).

To calculate how many grams are in a teragram, you can use the following formula:

Grams = Teragrams x 1,000,000

For example, let's say you have 3 teragrams. To find out how many grams this is, you would use the formula above:

Give the expression in terms of a, k, and t is g(t+1/k) = a2^(k(t+1/k)) = a2^kt * 2^(1/k)

The population doubles when P(t) = 2 * P(0), so we can set up the equation:

2 * 55 = 20^(5t)

Solving for t:

t = log(2)/(5 * log(20)) = log(2)/log(400)

The population doubles after approximately 0.173 years or 63.1 days.

g(t+1/k) = a2^(k(t+1/k)) = a2^kt * 2^(1/k)

Interpretation: g(t+1/k) is the population at time t+1/k, where a and k are positive constants. The population at t+1/k is equal to the population at time t multiplied by 2^(1/k). This means that if k is a large number, the population will change very little over time, if k is a small number, the population will change more quickly.

The number of white balls is equally likely to be any number between 1 and n − 1.

This problem can be solved by considering the number of ways to get a certain number of white balls in the bin. Since each ball can either be white or black, there are 2^n possible sequences of n balls in the bin.

Now consider the number of ways to get exactly k white balls in the bin. It can be done in the following way:

Choose k white balls out of n balls, which can be done in C(n, k) ways, and then arrange the k white balls and n-k black balls in (n-k + k)!/(n-k)!k! ways.

Therefore, the number of ways to get exactly k white balls in the bin is C(n, k)(n-k + k)!/(n-k)!k! = C(n, k)(n!)/(n-k)!k!.
